The problem

Two High-Value Services. Near-Zero Organic Visibility.

What the audit found

Day 1 findings

ADU construction and seismic retrofitting are two of the highest-demand, lowest-competition SEO categories in the East Bay California market. Devco offered both and was invisible for nearly all searches in both categories.

Position 1 for adu builders orinda was the single bright spot, confirmed by Voodoo. But Orinda is one city. Lafayette, Walnut Creek, Berkeley, Oakland, and Concord had no equivalent page and no ranking.

Seismic retrofitting page existed but was ranking position 21 for cost of seismic retrofit, a high-value informational query with strong conversion to project inquiry.

No FAQPage schema anywhere. No AI Overview eligibility. No structured answer content for either service category.

ADU builders Orinda (only bright spot)

1

city ranking, Orinda only

One city working and proven. Five other cities and a strong informational query sitting untouched. The model existed. It needed to be replicated.

02 / What we did

The plan we ran

Homerankr replicated the Orinda page model across 5 additional East Bay cities, rewrote the seismic retrofit page for AI Overview eligibility, expanded GBP across the East Bay metro, and published earthquake retrofit blog content for informational search coverage.

01
Weeks 1 to 3

Built ADU city pages for 5 additional East Bay cities

New ADU city pages built for Lafayette, Walnut Creek, Berkeley, Oakland, and Concord replicating the Orinda page structure with city-specific content. Each page addressing local ADU permit requirements for that city, typical lot sizes and ADU size limits, HOA restrictions where applicable, and ADU financing options specific to Contra Costa and Alameda Counties. LocalBusiness and FAQPage schema on every page.

02
Week 2

Rewrote seismic retrofit page for AI Overview eligibility

Seismic retrofitting service page rewritten with direct 50-word answers below every H2. FAQPage schema added with 8 questions targeting what does seismic retrofitting cost in Oakland, is my house required to be retrofitted in Alameda County, what is a cripple wall and why does it need retrofitting, and does seismic retrofitting increase home value. HowTo schema for the seismic retrofit inspection process.

03
Week 1

GBP expanded across Oakland and East Bay metro

GBP service area expanded from Lafayette/Orinda to full East Bay coverage: Oakland, Berkeley, Walnut Creek, Concord, San Leandro, San Mateo. Home Builder primary category maintained. ADU contractor, seismic retrofit specialist, and garage conversion contractor secondary categories added. 32 project photos uploaded with geo-tagged metadata from completed ADU and retrofit sites.

04
Week 3 onward

Earthquake retrofit blog content for informational AI search coverage

Two 1,200-word blog posts published: what homeowners need to know about mandatory seismic retrofit programs in Oakland, and the complete guide to ADU permits in Contra Costa County. Both posts with FAQPage schema and direct answer content. Both targeting the informational research phase before project inquiry.
